    What is the molar mass of N?

    Answer

    M(N) =
    14.007 g/mol

    Atomic weights: IUPAC standard values (CIAAW, 2024).

    Elemental nitrogen is made of N2 molecules: M(N2) = 28.014 g/mol = 0.028014 kg/mol.

    FAQ

    What is the molar mass of N?

    M(N) = 14.007 g/mol

    Why is the molar mass of nitrogen 14.007 and not 28?

    14.007 g/mol is the mass of one mole of N atoms. Elemental nitrogen is made of N₂ molecules: M(N₂) = 2 × 14.007 = 28.014 g/mol (28 in school problems); in SI units, 0.028014 kg/mol. In a problem about the gas, the molar mass of nitrogen is usually M(N₂).

    How many grams are in 2 moles of N?

    m = n × M = 2 mol × 14.007 g/mol = 28.014 g.
